I appreciate Adam was willing to pursue testing but I left feeling like I had to supply much of the clinical direction myself. I would have felt more reassured with clearer expertise and guidance regarding my symptoms and the possible causes. I felt like I was bringing the clinical direction. He did not seem very experienced with my symptom pattern. The visit didn't leave me feeling guided or reassured. I wanted more of a sense of expertise and confidence.

I felt like I was just another patient. That my concerns didn't really matter. That there was a cookie cutter response.
